"Waiting on" Wednesday: Standard Deviation

Graham Cavanaugh’s
second wife, Audra, is everything his first wife was not. She considers
herself privileged to live in the age of the hair towel, talks non-stop
through her epidural, labour and delivery, invites the doorman to move
in and the eccentric members of their son’s Origami Club to
Thanksgiving. She is charming and spontaneous and fun but life with her
can be exhausting.

In the midst of the day-to-day difficulties
and delights of marriage and raising a child with Asperger’s, his first
wife, Elspeth, reenters Graham’s life. Former spouses are hard to
categorize – are they friends, enemies, old flames, or just people who
know you really, really well? Graham starts to wonder: How can anyone
love two such different women? Did he make the right choice? Is there a
right choice? - from Goodreads
